Abstract:

Remote control devices borne by potential passengers are alerted to initiate a request for elevator service by beacons in the building. The beacon alert message includes a tag identifying the floor on which the beacon is located and a position on the floor at which the beacon is located. The floor description tags prevent transmissions of the remote device from being recognized on floors other than the floor on which the device was alerted by a beacon, whereby transmission power of the remote devices may be quite high to assure reception anywhere on the floor, while being ignored on adjacent floors. Tags descriptive of the location on the floor (such as east, west, or lobby area) allow early assignment of a call to an elevator, without causing a car to stop for that particular passenger unless the call is verified by the passenger being sensed in the immediate vicinity of the elevator, and a car call is not entered for the destination floor unless the passenger is sensed as being within the elevator cab, due to a remote device message including a cab descriptor tag.
